Integration of CBCT and a Skull Base Drilling Robot
نویسندگان
چکیده
The performance of a Skull Base Drilling Robot is limited in cadaver studies mainly due to registration error in current system. In this project, a C-arm cone-beam CT will be used to provide guidance and "no-fly zones" to the robot that properly accounted for anatomical deformations imparted during the surgery. Hopefully, this integration will reduce registration error and improve the performance of the robot in cadaver studies.

An integrated system for planning, navigation and robotic assistance for skull base surgery.
BACKGROUND We developed an image-guided robot system to provide mechanical assistance for skull base drilling, which is performed to gain access for some neurosurgical interventions, such as tumour resection. The motivation for introducing this robot was to improve safety by preventing the surgeon from accidentally damaging critical neurovascular structures during the drilling procedure. METH...
متن کاملImproved ultrasound-based navigation for robotic drilling at the lateral skull base
Sensitive structures of the lateral skull base demand for robotic procedures a higher precision than provided by standard navigation systems relying on CT scans. Keystone of our multisensor approach to improve accuracy is the use of ultrasound for local navigation. In this study we compare two different ultrasound techniques to measure human skull bone in vitro: (A) the classic echo technique a...
متن کاملCan Coffee Improve Surgical Robot Accuracy?
Transnasal skull base and sinus surgery is often assisted via image guidance systems (e.g. the Brainlab Kolibri [1] – Fig. 1) which show the real-time locations of surgical instruments with respect to the 3D map provided by preoperative volumetric medical images. Image guidance systems often employ optical tracking to measure in real time the locations of both surgical instruments and the patie...

OBJECTIVES The conical beam computed tomography (CBCT) technique presents an innovation of tomographic imaging systems and subsequent volumetric image reconstruction for dentistry. When compared with other methods of tomographic imaging CBCT is characterized by rapid volumetric image acquisition from a single low radiation dose scan of the patient. The NewTom (NewTom 9000; Quantitative Radiolog...

This case report presents an eight-year-old girl having periauricular swelling and severe pain during mouth opening on the right-side temporomandibular joint (TMJ). CBCT showed extensive destruction of the base of the skull and the roof of the glenoid fossa on the right side. The findings based on CT and MRI images with and without contrast are discussed herein. This report highlights a skull b...
